I have a 2009 Dodge Chager RT that I want to add Heades to. Service tells me there is now a kit available for so, but, this will cause the Check Engine Light to come on after a period of time and thus will cause failure when inspected, this being emmisons. Is this true? Why would a kit be available from Dodge Service, but cause inspection issues? Any info on this would be helpfull. Thnks to all.
